The advantages of laser marking on metal nameplates

Metal nameplate is a common identification plate in industrial production. Its main function is to convey to customers the manufacturer’s brand, trademark, product parameters, production date, production Specifications, QR codes and other information. The materials of metal nameplates mainly include copper, aluminum, stainless steel, alloys, etc. Because it is easy to store, wear-resistant, and has good appearance and texture, it is widely used.

Metal nameplate laser marking machine generally refers to fiber laser marking machine. It adopts non-contact processing without contacting the surface of the nameplate, and it does not damage the nameplate. At the same time, it also has marking High precision, fast speed, permanent marking and other characteristics.

The traditional marking methods of metal nameplates include silk printing and pad printing. The working principle of silk printing is very simple. Firstly, engrave the pattern to be printed on the steel plate, and then use the printing screen Printed on the surface of the nameplate. Pad printing is to first make a plate to be printed, engrave the intaglio plate on the steel plate, and then print it on the surface of the product with a silicone transfer head.

Compared with the metal nameplate laser marking machine, the disadvantages of silk screen and pad printing are as follows:

1. The wear resistance is poor. The metal nameplate uses silk printing and pad printing, and its wear resistance is much worse than that of laser marking.

2, the aesthetics is not high, the appearance of metal surface printing is relatively low-end, which is not suitable for some products with high requirements on the appearance of the nameplate.

3. It is not environmentally friendly. The screen printing process needs to use organic solvents and heavy metal elements and other chemical raw materials. These substances have certain toxicity. During the drying process of screen printing inks, volatile chemicals The raw materials gradually volatilize into the air, causing pollution to the air and the environment.

4. The environmental requirements are high. Due to production environment problems, the nameplates of some equipment have been immersed, high temperature, chemical pollution, etc., and the nameplates marked by traditional methods are more resistant Low, damage may occur.

The metal nameplate is marked with a laser marking machine. It only needs to be controlled by a computer. The operation is simple. It can print a variety of complex patterns, text, two-dimensional codes and other content. After the mark, the workpiece will not produce internal stress, ensure the original accuracy of the workpiece, and the mark will not fade due to environmental relations (touch, acid and alkaline gas, high temperature, low temperature, etc.), environmental protection and pollution-free, not easy to be tampered with. High anti-counterfeiting.
